    - pod for PNI::Mo and PNI::Node::Mo
    - added jquery-ui
    - added few File::Spec nodes
    - t/node folder

0.28  2012-02-28
    - PNI::Comment now is a node
    - updated deprecated paths method in PNI::GUI

0.27  2012-02-19
    - removed view stuff from model
    - avoid PAUSE indexing for nodes and Mo

0.26  2012-01-31
    - small bug fixes
    - removed tests from _finder.t, since they can fail if there are
      deprecated nodes installed in previous versions.

0.25  2012-01-30
    - fixed PNI::Node::Perlfunc Keys and Values failing in 0.24.1
    - can' t version it as 0.24.2 cause there is a problem with indexing:
      I will try to use the perlmodestyle way for next releases
    - added versioning policy as in perlmodstyle

0.24.1  2012-01-28
    - fixed test _file.t failing in 0.23

0.24    2012-01-28
    - merged with PNI::Node::Perlop and PNI::Node::Perlfunc so now a lot of
      nodes are included. This will be a great advantage since people will
      install and the core node with one *natural* command, i.e. cpan PNI.
    - dummy pni bin

0.23    2012-01-26
    - there will be only one distro! ;^) merged with PNI::Node::Perlvar,
      so now Perlvar nodes Basetime, Osname, Perl_version, Process_id
      are included.
    - basic structure waiting for PNI::GUI

0.22.1  2012-01-14
